computing the following: (a) test statistic (b) p-value ?=p= (c) If this was a two-tailed test, then the p-value is
Golf-course designers have become concerned that old courses are becoming obsolete since new technology has given golfers the ability to hit the ball so far. Designers, therefore, have proposed that new golf courses need to be built expecting that the average golfer can hit the ball more than 250250 yards on average. Suppose a random sample of 113113 golfers be chosen so that their mean driving distance is 252.9252.9 yards, with a standard deviation of 48.448.4.
Conduct a hypothesis test where ?0:?=250H0:μ=250 and ?1:?>250H1:μ>250 by computing the following:
(a) test statistic
(b) p-value ?=p=
(c) If this was a two-tailed test, then the p-value is
